the Indus River dolphin doesn't sleep as you or I do, or indeed as most mammals, for several hours at once. Instead, it takes microsleeps, naps that last for a few seconds, like a driver dozing at the wheel.

I wish I could do that!

More than that, I find that in viewing ourselves as one species out of hundreds of millions, we become more remarkable, not less so. No other animal that I have heard of can live so peaceably in such close quarters with so many individuals that are unrelated. No other animal routinely bothers to help the sick and the dying, or tries to save those hurt in an earthquake or flood.

Which is not to say that we are all we might wish to be. But in putting ourselves into our place in nature, in comparing ourselves with other species, we have a real hope of reaching a better understanding, and appreciation, of ourselves.
